I apologize in advance for asking it here in this thread, but I bet I'll get the fastest, most accurate response here - I finally took the time to call up Disney Movie Club and cancel my membership. It all went smoothly, and I can't log into my account any more (says it's been disabled), but I never received an email saying I had successfully cancelled (you know, for record keeping purposes, in case something happened later down the road and they tried charging me for movies).
I'm assuming I'm in the clear and can make another without having to worry about charges on my old one, right? And if anyone can post that promo code that gets you the extra movies/only 3 required movies for fulfillment, I'd appreciate it (so I don't have to hunt it down). Thanks a ton.
